1. No even splash water resistant but should be. Both ports USB and TF Card should be secured.2. 80 mA battery is not sufficient, 120 or 160 could be better.3. Blue LED blinks too many times -no needs- during the usage and shortens the battery life. Quick blink e.g 1/5sec should be considered by Manufacturer, Red LED in Radio Mode lights up permanently. It costs a battery.For those looking for cheapest BT earphones with built-in Radio,TF Card that's the best option.You will get really good product but unfortunately only sneeze could damage device.
